BitScope Chart Recorder

Unlike other data acquisition systems Chart is very high bandwidth and leverages the power of WaveMeter to capture, display and record AC or DC voltages, frequencies, periods and other signal statistics on multiple channels.

Features and benefits include:

Unlimited duration data logging

Wide bandwidth, DC to RF signals

Integrated realtime chart display

Multi-channel operation (up to 16)

Built-in auto-trigger oscilloscope

AC, DC, RMS & Min/Max voltages

Auto-locking frequency & period

Duty cycle, sample rate and more

User configurable record to disk

CSV files for spreadheet analysis

Anything WaveMeter can measure Chart can plot in real-time and record to disk. Any combination of BitScope channels may be used including logic channels for time interval, frequency, period and duty cycle measurements.

High Bandwidth Data Capture

BitScope Chart can capture waveforms utilizing the full bandwidth of BitScope.

This means signals from DC to very high frequency RF can be captured, analyzed and the signal statistics displayed and recorded as they evolve over time. The raw data may be recorded as well.

Chart is just as well suited to plotting the RF power of a radio transmitter as it is monitoring the operation of a power inverter or recording a slow charge voltage profile of a battery.

For example these six plots show the output level variations as frequency is swept over each range of a cheap RF signal generator driving a 50Ω load.

These ranges start at 100kHz and finish at 150MHz and exhibit some substantial output level variation.

The highest range is unable to drive the load adequately but it also shows the upper bound of the analysis band. The point is that any signal that can be measured via voltages or waveform statistics that is within the bandwidth of BitScope is suitable for capture with Chart.

Down the sides of the main display are the live capture measurements (on the right) and cursor time measurements (on the left) for each enabled channel.

The example on the right shows 8 frequencies generated by a simple counter (WaveLoop 0). The first channel (POD Ch A) is the WavePOD analog output frequency and the logic channels show the associated address line frequencies.

Any of these measurements may be clicked to select the channel for solo mode or to select it to see the waveform. The cursor may be dragged to any position to view measurements made in the past while live measurements continue.

Below the display are the channel measurements and the primary chart controls.For each channel a selected waveform statistic is displayed in a large font to make reading values from far away easy (e.g. while probing around a circuit).

Shown with the channel measurements is information about the connected BitScope (a BS120U on the first USB port in this example) as well as the Chart version as seen here:

To the right of the measurements are four primary chart controls which in this case select the signal parameter (Vrms), whether to display the live or cursor data (Cursor), the time duration over which to capture (1 hour) and whether to display voltages DC or AC referenced.

Advanced controls and application configuration options are available via the menus at the top of the application window and almost all operations have keyboard short-cuts available.
